UN DERFRAMEEFOR CARS.

To all whom it may concern:

Be it known that I, CHARLES S. SHALLEN- BERGER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Underframes for Cars, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of my improved underframe for cars; Fig. 2 is a detail of the means for connecting the side sills to the body bolster; Fig. 3 is a view similar to Fig. 2 illustrating a modified form; Fig. 4 illustrates a modified form of underframe; Fig. 5 is a longitudinal sectional view taken on the line 55 of Fig. 4; and Fig. 6 is a transverse sectional view taken on the line 66 of Fig. 5.

This invention relates to new and useful improvements in underframes for cars.

There are many wooden cars in use today, which, on account of the high price and scarcity of proper timber, are being abandoned because it is almost impossible to obtain the proper'timber necessary for repairs.

One of the principal objects of my invention, therefore, is to provide a metallic underframe of maximum strength and mini mum weight which can be used in wooden car construction, said underframe being capable of being placed under existing cars.

My improved underframe is composed of a small number of parts which are easy to assemble, and is adapted for use on various types of cars both new and old.

Referring to Fig. 1 of the drawings which illustrates my improved underframe applied to a wooden car in such manner that it constitutes an auxiliary underframe for supporting the car body, 1 indicates the longitudinal sills of the wooden underframe and 2 is the end sill thereof. This wooden underframe is supported by and secured to the auxiliary underframe.

3 is a body bolster, and 4 indicates short draft or center sills which are connected together at their outer ends by means of a short end sill or buffer block 5, said draft sills being .provided with pockets 6, for the reception of a-draft rigging. Where I refer to the Specification of Letters Patent.

buffer block 5 in the claims I mean to include a short end sill as well as a buffer block.

The draft sills, bolster and buffer block are preferably in the form of a single casting which constitutes the main end element of the underframe. W hen applied to a wooden car this end casting is preferably provided with abutments 7 and 8 on its upper face, which abutments engage the inner and outer faces res ectively of the wooden end sill. Center sifis 9 extend from bolster to bolster and are secured to inwardly extending portions of the end castings.

10 indicates side sills which are secured to the bolsters and have their end portions bent diagonally from the ends of the bolsters to the buffer blocks 5, the latter forming abutments for the ends of the side sills and being provided with wings 5 which are fastened to said sills.

If desired, cross bearers 11 may secured to the longitudinal sills intermediate the bolsters.

As the bufling shocks which are delivered 4 to the ends of the side sills tend to force these sills outwardly from the bolsters, I deem it advisable to provide means for rigidly secur ing them to said bolsters. VJhile this securing means may be constructed in various ways, I prefer the form shown in Figs. 1 and 2. In this form the upper face of the bolster is provided with a shoulder or abutment 12, and a bar 13 which is bolted to the bolster has one of its ends folded under or enlarged to engage said abutment 12 and its opposite end bent under the top flange of the side sill and bolted thereto. The lower flange of the side sill rests on the bolster and is prevented from moving outwardly by a lug 14 formed integral with the bolster. If desired, the side sill may also be secured to the bolster by means of rivets.

Fig. 3 illustrates a modified form of the means for securing the bolster to the side sills, in which bars 13 and 14* are secured to the bolster and bent around the flanges of the side sill 10 Inthe underframe illustrated in Figs. 4, 5

and 6, side sills connecting the body bolsters are dispensed with. The end casting used in this form is substantially the same as the casting shown in Flg. 1, said castmg comprising a bolster 3 short draft sills 4 and a buffer block 5 The bolster 3 is provided with an integral wing 15 which is riveted to the web of a center sill 16. The center sill is also connected to the bolster by means of an L-shaped member 17, said member being riveted to the web of the bolster and to the web of the center sill. 18 and 19 respectively indicate plates which are riveted to the top and bottom flanges of the bolster 3 and to the flanges of the center sill. Side members 20 which are preferably rolled channels are connected to the buffer block 5 and extend diagonally from said butler block to the ends of the body bolsters and thence inwardly to the center sill. The inner ends of the side members 20 lay against the center sill and are secured thereto. Bars 13 connect the members 20 to the bolster. The form of underframe just described is p articularly adapted for use on tank cars or wooden cars in which it is not deemed necessary to employ auxiliary side sills.

My improved underframe eliminates a large percentage of the material usually employed in the end portion of an underframe as the side sills which extend from the ends of the bolster to the butler block form the outside margin of the underframe at this point. \"Vhen this underframe is used as an auxiliary underframe on wooden cars, the wood sills can be relied on to support the load beyond the diagonal end portions of the side sills.

I am aware that minor changes in the con struction, arrangement and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
